Amorphophallus titanum ‘Titan Arum’ or ‘Corpse Flower’. This giant aroid from Sumatra can reach 20ft tall with its single, umbrella-like leaf, and its bloom is classed as the largest un-branched inflorescence in the word at over 9ft tall. The morbid ‘Corpse Flower’ name comes from the smell of rotting flesh and the color of spoiled meat associated with the bloom, pollinated by flies and beetles in its habitat. In cultivation it has been rare and never fails to be newsworthy when one blooms. Only a few private collections and botanical gardens had this giant in their collections due to its former rarity.
